IMPLEMENT FOR INSERTING PAPER-FASTENERS.

SPECIFICATION forming part of Letterslat'ent No. 638,242, datedSeptember 19, 1899-. Application filed December 21, 1898. erial No.699,930. (No model.)

' To aZZ whom it may concern.-

Be it known that I; CHARLES MAGNUs HAYES, a citizen of the UnitedStates, residing at Birmingham, in the county ofJefferson and State ofAlabama, have invented certain new and useful Improvements inPaper-Fastener- Inserting Implements and I do declare the following tobe a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to devices for attaching together papers and thelike, and contemplates the production of an implement by which theinsertion of the fastener may be easily and quickly accomplished.

The nature of my invention will be readily understood by reference tothe following'description and to the accompanying drawings, which form apart thereof.

In the drawings, Figure 1 is a perspective view illustrating the use ofthe fastener and my improved inserting implement. Fig. 2 is aperspective view of the fastener. Fig. 3 shows the blank from which thefastener is made. Fig. 4 is a vertical sectional View of the insertingimplement. Fig. 5 is a sectional view on line 5 5 of Fig. 4.

Referring to the drawings by letter, A denotes, the fastener, whichcomprises the head a and two pointed prongs a a. The fastener isconstructed by punching or otherwise making from sheet metal the blankshown in Fig. 8 and bending it to the form shown in Fig. 2.

The head a is centrally enlarged and is provided with a slot or aperturea, the length of which is slightly in excess of the width of the prongsa.

The inserting implement B comprises a head b and a blade I), the latterterminating The blade is provided near the head end with shoulders 12 band beyond the shoulders the blade flatwise is provided on oppositesides with longitudinal depressions or grooves 12 b, the end of thedepressions or grooves nearest the point or edge of the blade having aninclined approach 12 In practice the fastener is slipped .over theblade, the latter occupying the slot or aperture (1 and the prongs a,which are'at each side of the blade, occupying the depressions orgrooves therein. The point of the blade is then forced by hand or otherpressure through the sheets, and further pressure being applied theblade entersup to the shoulders h The prongs of the fastener are carriedwith the blade into the puncture,- the engagement of the head a by theshoulders insuring the in sertion of the fastener up to its head. Thefriction between the sides of the puncture and the fastener-pron gs isrelatively greater than the friction between the prongs and the blade,-so that when the latter is withdrawn the fas= tener remains, and theexposed length of its prongs may then be oppositely bent over againstthe paper in the usual manner. The provision of the inclined approachesto the depressions obviously facilitates the with drawal and separationof the blade from the fastener. By reference to Fig. 5 it will beobserved that the blade is for a considerable portion of its length of Iform, thus insuring great strength and rigidity, qualities which areessential by reason of the strain to which the blade is subjected inpractice.

Aside from the strength and durability of the instrument there iseconomy in the pro= duction and high efficiency in operation.

The fastener may be of any desired size, and likewise the instrument;but I prefer to make the latter of such dimensions as will enable theuse in connection therewith of fasteners of varying sizes.

I claim as my invention- An implement for inserting paper-fastenershaving a pointed blade grooved intermediate of its ends and providedwith inclined approaches b at the lower end of the grooves, andshoulders 12 at the upper end thereof, that portion of the blade belowthe grooved portion being ungrooved, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES MAGNUS HAYES.
